Quality Control provides the necessary assurance that your images contain all the information possible for the delivered dose.
GAMMEX RMI's Mammographic Quality Control Kit RMI128B is used at every type of mammography facility, from small clinics to large medical centres. Each kit is complete and will provide you with the tools to perform the following tests : Image quality, Film/screen contact, kVp accuracy, Automatic exposure control reproduceability, Timer accuracy, half value layer, Focal spot size, Output reproductibility and linearity.
''Rachel'' Anthropomorphic Breast Phantom RMI 169
The ''Rachel'' Anthropomorphic Breast Phantom RMI 169 provides an image with the detail and contrast of an actual mammogram. The phantom may be used for evaluation of the effects of variable conditions encountered in mammography. These include differences between machines, varying exposure parameters, processing conditions, and film/screen combination.
The phantom consist of three parts ; the base BR-12 (breast equivelent) material, the high resolution film layer, and the outer case. The base material is moulded BR-12, formed to provide the variations in thickness which result in differences in radiographic optical density. The film layer is a mercury-intensified x-ray film of an actual mammogram that has been digitaly processed. This film, when aligned with the base, produces a fine detailed structure in the image. The outer case provides protection and allows for consistent positioning in the x-ray field. The lip on the edge of the outer case fits against the compression paddle and the table edge to give consistent and realistic positioning.
Anthropomorphic Breast Phantom RMI 165
Moulded from Gamex RMI tissue equivalent to breast material, the Anthropomorphic Breast Phantom RMI provides an image the size and shape of a 5cm compressed breast. The special design provides low, medium and high detail resolution components for a precise, life like breast image. The RMI 165 tests mammographic systems under near clinical conditions and has the same attenuation characteristics as a human breast or 50% glandular tissue and 50% adipose tissue.
The phantom and inserts provide an exellent tool for demonstrating the clinical effects of variations in kV, density, film screen combination and processing conditions.
Digital Mammographic Phantom RMI 156S
The Digital Mammography Phantom RMI 156S is a small version of the Mammographic Accreditation Phantom RMI156. The RMI156S is used for monitoring digital mammography systems currently used for stereotactic biopsy and localization.
